Basement remodel – existing insulation
What a great forum–just found it the other day and have spent hours on it already!
I’m planning to finish the walk-out basement in my 2-year old spec house. Three walls are poured concrete, and these walls are covered with a fairly thin blanket of fiberglass insulation w/vapor barrier that’s powder-nailed to the concrete walls (the basement is heated & cooled already). Looks like a big padded room (which I may need as I get farther along in this). I’m planning on building stud walls to overlay the concrete walls, as floor space isn’t a problem.
My question is: should I rip out all this existing insulation, then build the new walls 1″ or so away, and install all new insulation & vapor barrier in the stud cavities? Or should I leave the insulation, and build the new walls say 4″ away from the concrete to avoid compressing the existing insulation? My thinking is that everything seems to work pretty well now, i.e. basement stays comfortable in summer & winter, no moisture problems, so should I be fixing it if it ain’t broke?
Thanks in advance,
